Keep your RV's indicator lights, courtesy lights, and instrument panel lamps working with the correct OEM-spec replacement. The Camco No. 53 bulb is a direct drop-in for a wide range of automotive and RV applications that use the miniature single contact bayonet base, and it is packaged in a two-pack so you have a spare on hand when you need it most.
The No. 53 is one of the most common miniature bayonet bulbs found in RVs, trailers, and tow vehicles. It appears in instrument clusters, warning indicator panels, courtesy and step lighting fixtures, and small accent or clearance lamp sockets that require a low-wattage, 14-volt source. At only 1.7 watts, it draws minimal current -- a real advantage in 12V DC systems where battery conservation matters.
Camco part number 54711 (vendor reference 18-1222) packages two bulbs together, giving you a ready spare without hunting down a hardware store mid-trip. The clear glass envelope provides a clean, neutral light output suited to both functional indicator sockets and decorative fixtures.
Single contact bayonet (BA9s-style) base fits the most common low-wattage indicator sockets found in RVs and tow vehicles.
At 1.7 watts and 14.4 volts, this bulb places minimal load on your 12V DC system -- ideal for boondocking and battery-conscious rigs.
Rated service life of up to 1,000 hours under normal operating conditions, reducing how often you need to replace indicator and accent lamps.
Each package contains two No. 53 bulbs. Keep one installed and store the second as an on-board spare -- a smart practice for any RV owner.
The No. 53 bulb is used across a broad range of fixtures and panels. Typical locations where you will find this bulb in RVs and trailers include:
Indicator and warning lamps are easy to overlook until one burns out at the worst possible moment -- a campsite after dark, a pre-departure walk-around, or a DOT inspection stop. Because the No. 53 is used in so many sockets throughout a typical RV, keeping a two-pack in your toolbox means you are never caught without the right replacement.
